I have a question about building beehives. One of the people I work with has a large cabinet shop. I just filled my pick up truck with 4 loads of Poplar, Mahogany, Cedar, Oak, and some other exotic hardwoods. Does anyone know of any woods that would be toxic to bees? I also have some cabinet grade unfinished hardwood plywood. The plywood has been treated with a non-toxic soy based product for termites. The product is not poison but it makes the wood so the termites don't like the taste I guess. Okay for bees? I was planning on using the ply for top and bottom boards and the hardwood for hive bodies. I have enough free wood for about 50-60 hives. Any advice would be appreciated.
